Also, regarding the Prinsu mounting feet that you linked, verify they’ll work with your tent manufacture.@McDuff123 I see that you have some mounting hardware and some spacers on the end of your rack. Is that something you rigged yourself? It appears Prinsu has some mounting brackets for RTTs, but I'm not sure which height to get. And of course Prinsu's phone number is a busy signal.

I have a Free Spirit tent, and the feet don’t integrate with it. I bought them (might still have them...would sell cheap) but then realized they won’t work for me. That’s when I bought the FrontRunner QR mounts.
